Symptoms

This problem occurs when the following conditions are true:

  • You deploy Windows Server 2012 R2 domain controllers (DC) in your Active Directory domain in which the Active Directory Recycle Bin is disabled.

When this problem occurs, the following event messages are logged in the application log:
